In the paper we present two novel interactive tools, Emotion Disc and Emotion Squares, to explore the facial expression space. They map navigation in a two-dimensional circle, by the first tool, or in two two-dimensional squares, by the second tool, to the high-dimensional parameter space of facial expressions, by using a small number of predefined reference expressions. They can be used as exploration tools by researchers, or as control devices by end-users to put expressions on the face of embodied agents or avatars in applications like games, telepresence and education.
a b s t r a c tThis paper describes an agent-based platform for the allocation of loads in distributed transportation logistics, developed as a collaboration between CWI, Dutch National Center for Mathematics and Computer Science, Amsterdam and Vos Logistics Organizing, Nijmegen, The Netherlands.The platform follows a real business scenario proposed by Vos, and it involves a set of agents bidding for transportation loads to be distributed from a central depot in the Netherlands to different locations across Germany. The platform supports both human agents (i.e. transportation planners), who can bid through specialized planning and bidding interfaces, as well as automated, software agents. We exemplify how the proposed platform can be used to test both the bidding behaviour of human logistics planners, as well as the performance of automated auction bidding strategies, developed for such settings.The paper first introduces the business problem setting and then describes the architecture and main characteristics of our auction platform. We conclude with a preliminary discussion of our experience from a human bidding experiment, involving Vos planners competing for orders both against each other and against some (simple) automated strategies.
Human faces are attractive and effective in every-day communication. In human-computer interaction, because of the lack of sufficient knowledge and appropriate tools to model and animate realistic 3D faces, 2D cartoon faces are feasible alternatives with the extra appeal of 'beyond realism' features. We discuss CharToon, an interactive system to design and animate 2D cartoon faces. We give illustrations (also movies on CD) of the expressive and artistic effects which can be produced. CharToon is fully implemented in Java, allows real-time animation on PCs and through the Web. It has been used with success by different types of users.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
